Well separated with noticeable difference in brightness.

STF 227 (**)
Name: STF227, iota Tri, 6 Tri
Type: **
Constellation: Tri

70mm f/5.7, 57x
At 44x even separable with a clear difference in brightness, whereby the companion is almost outshone by the primary component. At 57x easy to separate. Primary component shines in bright orange, companion slightly orange. Beautiful sight together with STF232 in one field of view!

70mm f/5.7, 22x
Very beautiful view! With all used magnifications together with iota Tri (6 Tri) in one field of view. Separable at 22x, but the components are still quite close together and appear similarly bright. At 44x easy to separate with little difference in brightness. At 57x a very small color difference is visible without being able to clearly name the colors. STF232 was sketched together with 6 Tri.
